I have a four stage centrifugal process gas compressor that has a wash liquid and a water injection used for anti-fouling and evaporative cooling of the process gas, respectively. I'm looking for guidance on how to best determine the maximum amount of water injection (for cooling purposes) that each stage can withstand without detrimental effects to the compressor (wash liquid injection rate will stay constant). I understand that the rule of thumb for wash liquid injection is no more than 3% of the mass flow rate, but does this the same for the cooling water injection? Is the 3% rule of thumb for total liquid injection (wash liquid plus water injection) or just wash liquid injection?
Any guidance that anyone may be able to give on this subject would be greatly appreciated.
